Incoming new snow accumulation could be over a foot. This precipitation will collect on a highly variable snowpack that resides in our mountains. Be suspicious of areas where a deeper snowpack exists such as cross-loaded gullies & abrupt terrain changes.
Our storm is coming in with ferrousioucly high winds. Strong sustained winds could average in the 50 mph range with hurricane-like gusts reaching 110 mph! Snow will be transported to places where a deeper pack resides, especially on Northeast through Eastern aspects. Winds will help increase the storm slabs density, making it more prone to propagation.
Although less reactive lately, due to warm temps & a period devoid of new snow, the persistent slab issue has not fully dissolved. Whumphing & cracking can still be observed in areas where there is a deeper snowpack. Understanding where these weak layer pockets linger is paramount to having a safe day in the mountains.
The structure of persistent slabs still exists within the snowpack but has been subdued by sintering & spring-like weather. The incoming weather system can have an effect on those buried weak layers by adding stress. The area we dug in whumphed upon our travel across it. Our pit revealed multiple crusts & facet layers with a denser base on top of the ground. Tests were relatively inconclusive with irregular fracture plains in weak layers with moderate pressure. Small surface hoar & suspected near surface faceting below a thin sun crust was observed. Winds have scalloped the snow surface & deposits amongst the sedges were peculiar near ridgeline at 10,500'.
A tour yesterday provided a resurgence of hope for our dismal season. Dry & wind-effected snow pockets are there, although it takes a keen eye to discern what is safest to ride. Whumphing on flatter terrain lower amidst trees is still unsettling to those paying attention.

Yesterday into this morning we can expect above average temperatures & strong winds. An aggressively windy low pressure system will settle over us this afternoon into Friday with snow showers likely. Accumulations have been down-graded for totals but white-out conditions will take place. Higher alpine areas will see the heaviest effects of wind & snowfall. Projections foresee another storm in the mix for the weekend.
